So here's my dilemma, I want to change the Bose HU i have in my '06 G coupe with the AVH-P6800DVD. Only problem is i have the stock navi and bluetooth. I am willing to give up the bluetooth and the dual climate control, but Navi is pretty much useless unless you have voice guideance and everyone shop (and even crutchfield too) has told me that if i replace the bose HU with an aftermarket, I will lose the OEM bluetooth functionallity and the voice guidance from the Navi. Does anyone know of anyway to overcome this? I dont want to have 2 navi's, thats kind of pointless to me and a waste of money (to me, to each their own), and the avh-p6800 has everything i want. Please if anyone knows the answer to this please let me know!!!! Worst case i'll just go with the Alpine Imprint PXE-H650...thanks
